Title: Improvements in or relating to frequency transposing apparatus
IPC: H03J3/28
Filed: 1945-07-06
Abstract: 598,571. Frequency converters. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 6, 1945, No. 17331. Convention date, April 20, 1944. [Class 40 (v)] In a frequency converter employing a number of fixed heterodyning frequencies, at least one of the tuning systems associated with the input and output circuits comprises means for displacing one element of a tuning device for varying the frequency continuously, and means for moving the other element of the tuning device in discrete steps corresponding to the choice of heterodyning frequency. In Fig. 1, mixer stage M has input and output circuits comprising capacitors C1, CO respectively with rotors ganged through gears E to produce identical variations in frequency during rotation. Control shaft T operates commutator K to select one of ten heterodyning frequencies Fq and simultaneously rotates stator C<1>1 about shaft U1 to produce discrete changes in capacity corresponding to the change in frequency Fq. In a modification, Fig. 2, cams A1, A0 move plates C<1>1, C<1>0 laterally with respect to their complementary plates C<11>1, C<11>0, to produce continuous variation in input frequency, while the discrete steps. in input frequency are produced by cam B1 on the same shaft T as commutator K. Alternatively, cam B1 may be eliminated by moving capacitor C1 bodily in steps about the axis of rotation of cam A1. Specification 580,528 is referred to.

Title: Radio beacon with quadrant identification
IPC: G01S19/50
Filed: 1942-12-11
Abstract: 560,364. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. Dec. 11, 1942, No. 17652. Convention date, Dec. 17, 1941. [Class 40 (v)] A radio beacon of the equi-signal overlapping-beam type is provided with an auxiliary beacon of similar type arranged at right-angles to the first, so that the pilot of an aircraft can determine in which quadrant he is, i.e. whether he is approaching or receding from the beacon. Fig. 2 shows the radiation patterns 200, 201 of the main and auxiliary beacons respectively. The two beams of the main beacon are continuously modulated by signals of different frequency, say 90 and 150 c.p.s., whereas the beams of the auxiliary beacon are modulated by the same tone frequency, say 1000, and keyed alternately to produce A, N or like signals. A pilot in the NW quadrant thus picks up signals A and 90, one in the NE quadrant receives N and 90, and so on. In Fig. 1, the antenna units 2, 3, 4 constitute the main beacon and 2A, 3A, 4A the auxiliary beacon. The carrier source 1 is connected through separate modulators 10, 11 (for frequencies 90, 150) and balancing network 22 to unit 3 via circuit 17 and to units 2, 4 by circuit 12, units 2, 4 radiating side-band frequencies only. The source 1 is also connected through a balanced modulator 14 (for frequency 1000) to unit 3A via circuit 17A and to units 2A, 4A through an A-N keyed reversing switch 16. The feed line 12 between units 2, 4 is provided with a transposition so that these units are fed in phase opposition. Feed line 12A between units 2A, 4A is similar. To prevent transfer of energy by induction between units 3, 3A, which are near each other, a compensation connection between circuits 17, 17A is made through phase-shifter 19, and prevention of radiation of the carrier frequency by the side radiators 2, 4 (due to radiation from 3) is effected by making the line 12 of a particular length which is determined experimentally. Specification 550,633 is referred to.
